Research ArticleOpen accessEvery word in the titleEffect of Dose-Response of Zinc and Manganese on Siderophores ProductionMehri Ines, Khessairi Amel, Turki Yousra et al.Problem statement: This study was conducted to find and determine whether the siderophores of the four environmental Pseudomonas spp. isolates possess a sequestering activity towards essential transition metals (Zn and Mn) other than iron. Approach: Four fluorescent Pseudomonads isolated from various environments, were characterized analytically (Isoelectric focusing), biologically (pyoverdine-mediated uptake) and genetically (16S rDNA sequencing). By means of spectrophotometric measurements, … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 10 Mar 2012 · 7,768 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsIncreasing Plant Health using Plant Growth Regulator from Rice RhizobacteriaMaimuna Nontji, Ayu K. Parawansa, Saida Saida et al.Plant health is a very important factor in the agriculture system. The presence of plant hormones such as Auxin, gibberellic acid, and siderophores with variation numbers in the plant gives different effects on plant health. Related to the environment rich with rhizobacteria, they have a unique function because rhizobacteria can produce a chemical compound known as Plant Growth Promoting Rhizobacteria … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 3 Jan 2023 · 6,031 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhanced Survival and Nodule Occupancy of Pigeon pea Nodulating Rhizobium sp. ST1 expressing fegA Gene of Bradyrhizobium japonicum 61A152Falguni R. Joshi, Dhwani K. Desai, G. Archana, Anjana J. DesaiProblem statement: Rhizobial isolates belonging to genera (Rhizobium sp. and Mesorhizobium sp.) in our laboratory produced only catecholate type of siderophores. Although FhuA and FegA (ferrichrome receptors) homologs were found to be present in the sequenced genomes of few rhizobia (e.g., 1 in R. etli and 2 in Mesorhizobium sp. BNC1), laboratory isolates of the corresponding genera failed to utilize … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 30 Jun 2009 · 7,865 accessesView PDF Cite
